Yep. Although from what I've been reading it seems that compiling with no-sse2 means QT5 may not perform as well.
Also it seems that it's possible for Linux distros to provide both an SSE and non-SSE version of the relevant library. See
here for a good (technical) summary of the issue, and
here for a related bug report.
It looks like Ubuntu - and therefore Xubuntu - is using this mechanism. HOWEVER Calibre supplies its own QT5 libraries so you'd probably need to build Calibre yourself. Sigil I think would use the system libraries if possible.
All of which is fascinating to some like me, but probably a bit of a tangent on a thread where we're discussing what's easy.
Oh and Greg, since you're already running Linux. You can check your CPU capability easily with:
Look for sse2 in the output. HTH.
